It need not have any symmetry.
Nothing. (Except if you count z axis and you get into 3D!)
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
(dali mi bannana!) it mean that its a radical of 2 shapes + a triangle divided by guwno
There is no such thing as a 3D triangle.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
3D shapes don't have lines of symmetry they have plane's of symmetry.
A cube has three planes of symmetry.
No.
A 3D hexagon.
No. A 3D triangle would be a triangular based pyramid.
